this question explanation ​

Answer 1

Explanation:

Zinc granules on treating with an acid X, form the Zinc sulphate (ZnSO4) salt along with the evolution of a gas Y which burns with a pop sound when brought near to a burning candle. Identify the acid X and gas evolved Y.

a) X- Sulphuric acid and Y- Oxygen gas

b) X- Hydrochloric acid and Y- Oxygen gas

c) X- Sulphuric acid and Y- Hydrogen gas✔

d) X- Hydrochloric acid and Y- Hydrogen gas

Explaination :-

Zn + X → ZnSO4 + Y

As we know that :-

• Hydrogen gas burns with pop sound when brought near to a burning candle.

Now,

It's cleared that Y is Hydrogen gas.

And

Zinc sulphate is formed in the reaction. It means, the acid is sulphuric acid which gives it's sulphate ion(SO4²-) to Zn(Zn²+) for the formation of ZnSO4.

Hence,

X- Sulphuric acid

Y- Hydrogen gas

Chemical equation :-

Zn + H2SO4 → ZnSO4 + H2↑

Therefore,

Option C is correct.
